The Pentair 263042Z is a factory replacement kit designed to rebuild a 2-inch 2-way CPVC check or diverter valve body. It allows service professionals to restore proper sealing and function without replacing the full valve body, saving time and cost.
Key Features
- OEM rebuild kit for Pentair CPVC check and diverter valves (sized for 1½″ to 2½″ capacity, primarily 2″ bodies).
- Includes clear inspection lid, new O-ring seal, replacement flapper/slam plate, and stainless screws for secure assembly.
- High quality materials—CPVC lid, chemical-resistant components designed for pool/spa plumbing environments.
- Service part allows valve bodies to be restored rather than replaced, reducing time and material cost for pool servicing.

Installation & Compatibility Notes
Before installing, isolate and depressurize the valve body. Remove the old lid and worn components. Clean the seating surfaces. Install the new O-ring, ensure the new flapper moves freely, and fasten the screws evenly. Tighten to recommended torque. After reassembly, restore flow and verify the valve seals and functions correctly under operating conditions.
Maintenance Tips
- Inspect the valve lid and O-ring annually for cracks, warping or wear.
- For resin pool systems, ensure the flapper is not sticking or showing wear patterns.
- Replace the kit if flow reduction or back-flow is observed—worn flapper or seal may cause performance issues.
- Keep spare kits on hand for fast service turnarounds.
